Abstract (en)
A plurality of cache servers, connected to a packet forwarding apparatus, forwarding a packet transmitted and received between a storage apparatus that holds a content under management in store and a user terminal, temporarily holds at least part of the content under management in store. A controller decides an on-screen resolution at the terminal, based on information contained in a content request message from the terminal, and selects a cache server that holds a content of the on-screen resolution in store. The controller instructs the selected cache server to deliver the content. The cache server instructed calculates a bit rate, with which a content is sent out, based on a signal received from the terminal. The cache server reads out a file or a stream of the content requested from the terminal. The file or the stream read out is to have the on-screen resolution and a bit rate not higher than the calculated bit rate. The file or stream is stored in a packet of a predetermined protocol and transmitted. The content is to be delivered without reducing the user's QoE.
